It doesn't really matter, but probably best to put your own. The eShop's region is determined by the region of your 3DS anyway.
There will be an online shop called the eShop and I believe it will have downloadable 3DS games. But about the DSTWO part, I'm not sure if you'll be able to put 3DS games onto it. Just in case, you may wanna check the main site.
There Are 2 Ways 1. Buy Pictobits From The eShop. 2. Put Real Music In The 3DS Sound Section, Play A Song, Press The Button With The 4 Squares, Then Press 8 bit.
No, the 3DS will not read roms that are placed on the SD card. It will not read any unregistered game data from the eShop either if it was not bought on that specific 3DS (except for system transfer)
Download copies of any eShop game are locked to one 3DS; even if you insert your console's SD card in another 3DS, the data specific to download games is unreadable. The only way around this would be to initiate a System Transfer, then insert the SD card once the process has finished.
You buy ds or 3ds games and then put them in your 3ds.
No, but there is 3DS sound which Plays music. all you need is a SD card with some MP3 Music, put the SD card in the 3DS. then go on 3DS sound then, you should be able to play your music.
Not entirely...the 3DS comes downloaded with augmented reality games which are all 3d. It doesn't matter what game you put in it. It has a 3d slider if you want it off or on or even in between. All games are 3d on this thing! :)
Your 3DS should have came with a 2 GB SD card. If you have an SD card reader on your computer, plug in your card to your computer, then put whatever music you want on the sd card. Plug the sd card back into your 3DS, and turn on the music channel.
Unless you have a Japanese 3DS, you can't.
No.
no you dont need to put password to activate your 3DS in the beginning, you put your own code in the first time you turn on and use you 3DS.
It's not going to break the 3DS, but because it says to do so on the instructions, you should really follow them.
